A Refutation of All Proposed Calendars

Funny, because, alas, so much of it is true.

This is not my material – for the original article, click on the title.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You advocate a ________ approach to calendar reform

You advocate a

( ) lunisolar ( ) atomic ( ) metric ( ) Luddite ( ) overly simplistic

approach to calendar reform. Your idea will not work. Here is why:

( ) solar years are real and the calendar year needs to sync with them
( ) solar days are real and the calendar day needs to sync with them
( ) the solar year cannot be evenly divided into solar days
( ) the solar day cannot be evenly divided into SI seconds
( ) the length of the solar day is not constant

( ) the lunar month cannot be evenly divided into solar days
( ) the solar year cannot be evenly divided into lunar months
( ) having months of different lengths is irritating
( ) having months which vary in length from year to year is maddening
( ) having one or two days per year which are part of no month is stupid
( ) your name for the thirteenth month is questionable

( ) the lunar month cannot be evenly divided into seven-day weeks
( ) the solar year cannot be evenly divided into seven-day weeks
( ) every civilisation in the world is settled on a seven-day week
( ) having one or two days per year with no day of the week is asinine

( ) requiring people to manually adjust their clocks is idiotic
( ) local time should not be discontinuous
( ) local time should not go backwards
( ) people like to go to work/school at the same time every day all year round
( ) no amount of clock-moving can increase the amount of solar energy received by Earth
( ) "daylight saving" doesn't

( ) UTC already solves that problem
( ) zoneinfo already solves that problem
( ) rearranging time zones yet again would make the zoneinfo database larger,
    not smaller
( ) the day of the week shouldn't change in the middle of the solar day
( ) local "midnight" should be the middle of the local night
( ) I shouldn't need to adjust my wristwatch every few miles

( ) there needs to be a year 0 and negative year numbers
( ) no, we don't know what year the Big Bang happened
( ) years which count down instead of up are not very funny
( ) planetary-scale engineering is impractical
( ) not every part of the world has four recognisable seasons
( ) "sunrise" and "sunset" are meaningless terms at the poles
( ) Greenwich is not unambiguously inferior to any other possible prime meridian
( ) the Earth is not, in fact, a cube
( ) high-tech applications need far more accuracy than your scheme allows
( ) leap seconds have been a fact of life for more than forty years
( ) leap seconds are more frequent than leap years
( ) TAI already solves that problem
( ) most of history can't be renumbered with atomic accuracy
( ) everybody in the world is already used to sexagesimal time divisions
( ) date formats need to be unambiguous
( ) abbreviated date formats should be possible and still unambiguous
( ) a leading zero on the year number solves nothing
( ) date arithmetic needs to be as easy as possible
( ) 13-digit numbers are difficult for humans to compare, even qualitatively

Specifically, your plan fails to account for:

( ) humans
( ) clocks
( ) computers
( ) the Moon
( ) the inconsistent rotational and orbital characteristics of Earth
( ) rational hatred for arbitrary change
( ) unpopularity of weird new month and day names
( ) total incompatibility with the SI second
( ) general relativity

and the following philosophical objections may also apply:

( ) BC and AD aren't
( ) technically, our calendar is already atomic
( ) they tried that in France once and it didn't take
( ) nobody is about to renumber every event in history
( ) good luck trying to move the Fourth of July
( ) nobody cares what year you were born
( ) the history of calendar reform is horrifically complicated and no amount of
    further calendar reform can make it simpler

Furthermore, this is what I think about you:

( ) sorry, but I don't think it would work
( ) this is a stupid idea, and you're a stupid person for suggesting it
( ) please just shut up and fix your broken date/time code
